What do I mean??
Well, you know, when Mark is dancing in the disco not the first time when in talking to Rollergirl, I mean the second time, when he does the coreography using very difficult moves from disco dancing. That's what I mean. Got it?

This is going to date me, but ah folks, we did that sort of dancing when I was in college!! Part of that which Mark does is called "the Bump". It isn't that hard to do.
I was in school when "Saturday Night Fever" was "the big deal" (w/ John Travolta). When I saw Mark's dance scene, it really took me back. He was so cute--he really did a great job, too. Hard to believe he was just a little kid when the 70s happened, hee-hee!
